A novel dioxane nucleoside for chemotherapy, 2(R)-(5-fluorouracil-1-yl)-5(R)-hydroxymethyl-3(R)-(uracil-1-yl)-1,4-dioxane and its 2(S)-isomer, were conveniently synthesized from uridine with several steps including periodate oxidation, partial reduction to form hemiacetals, and glycosidation of the second base, 5-fluorouracil, using stannic chloride as the catalyst.
